Nexus S SIM Connector (faulty)??

I have a brand new Nexus S that I believe has a faulty SIM slot. I saw one of the middle pins broken/missing. Strangely, one of my SIMs (Chatr Wireless from Canada) works fine - no other SIM works.
Any ideas if this is an easy repair or should I take this to Samsung for a warranty repair?
Thanks!

a buyer of mine is having the same issue
on your sim that is working
can u post a pic of your working to our non working thanks

Sure - I'm trying to get it replaced. If that doesn't happen, will get the phone back and post a picture.

Have attached the following. Sorry about the blurry-cam. My iphone 4 doesn't take great pictures - also the Nexus S still had the plastic wrappers.
The last picture that shows "No SIM" is actually with a SIM card inside.
If you find a fix - do share.

thanks can u post a picture of the simcard slot with out the simcard thanks

I have seen the no sim error on my phone after keeping it in my pocket during a mtb ride. I just figured the bumps jarred the sim around.

Here are the 2 pics of the sim card slot without the SIM. Notice the middle gold connector missing/broken? Am pretty sure that's the reason it's not reading the SIM. Chatr SIMs might not be using the middle SIM point of contact.

Update: Quick fix. Got a thin conductor strip and placed it at the entrance of the missing middle gold connector and lo-behold it's reading all SIMs now. Seems like a proper solder will fix it for sure....for now this will work!

[Q] [GT-i9020T] Almost repaired after water, but no signal and SIM detected

Hi,
After a water damage I opened my Nexus S [GT-i9020T] and cleaned everything with eletric contact cleaner. Everything is working fine, except for no signal, but the operator name (from SIM) appears in the screen.
I tried with Gingerbread and now with Crossbone 0.2.5, wifi works perfectly.
I cleaned the antenna gold points too, anybody can help to find where could be the problem or sugest replacement parts and where to find?
Thanks a lot,
ticofortes

Sounds like your radio might of gotten damaged also. Try to find stock Odin images for your device and try re-flashing it.

You know those gold pins are nfc right? Radio is down the right side of phone under case(looking at the screen)

mabry, I tried stock image (android.clients.google.com/packages/ota/google_crespo/1ada25375426.signed-soju-ota-189904.1ada2537.zip) and radio still not working.
DarkhShadow, please take a look at the attached image there are some contact points what i think is for radio antena, can you confirm that?
So I think my radio is damage, please where is it located? Where can I buy replacement parts or any alternative method to repair it?
Thanks all!

Looks like you got you picture from the above link, I would take apart to the point I am confident I can put it back together and use warm air blowing over it to dry it out over a day or so.
Contact cleaner may get most of the water out but not all of it. that is what I would do if I was in your position, before buying new parts for it.

Yes Gazoo222, I used this site.
I will try this drying procedure and come back in two days.
Thanks!

Just in case if it don't work, do you think the problem is in SIM card board?
(h t t p : / / guide-images.ifixit.net/igi/fDHYCvcIUepftlOQ.medium)
Or the antenna can be damaged with water too?
Is there any way to diagnose it better?
Thanks all!

they could be, but I think the radio is on the other side because if I cover it with my hand my wifi and phone signal drop a fair bit
You could try asking Adam outlet, ik he's probably poked around Nexus S hardware a fair bit

The antenna uses current and has very little resistance, so yes if it shorts out it could cause damage

Didn't work guys, I'll buy the sim board (link bellow) and replace it, what do you think? Tks!

After a lot of months waiting I found this and replace it without sucess the phone still identify the sim card but no signal.
I don't have more ideas... Is it possible the antenna is in short?
Tks!

Replaced Digitizer, now No Internet Connection in status bar

Like the title says, I replaced the digitizer, but now my phone either isn't recognizing my SIM card, or somehow the antenna isn't working. I can connect to my home wifi network, I have full audio, full capacitive buttons and vibration....but signal bar just shows empty (i'm using CM10).
I've put my SIM into my other phone, everything works fine. I've checked all of the connectors on the motherboard, everything is connected and nothing is loose or pinched anywhere. Can someone give me a layout of which connections control what?
thanks.

Remember that there's actually two different antennas. My suggestion would be to recheck each connection and make sure there's a solid click when you connect it

the top connector came off the wire when I snapped it from the motherboard. I crimped the wire back in place but maybe I sould solder.

Crimp should work if the center pin is still making contact with the wire. Soldering shouldn't hurt anything that I can think of

Update, I've purchased a replacement micro-coax cable, that fits correctly, but still have no signal coming to my phone for whatever reason. Any ideas, maybe getting a crappy g2x for parts and using it's cable?

Yup, not too sure what's happening. I literally did NOTHING else to the phone except accidentally rip off the connection on the lower end of the phone. I still get Wifi, so I know nothing internally is broken. I need to call tmo on the off chance this phone got locked due to previous owner payment or reported lost or stolen. It was an LG branded, g2x, though, which doesn't get sold throught tmo.

The LG brand could mean that the digitizer was previously replaced. It sounds like a very peculiar situation you are in. Replacement parts idea is probably best if you have looked over everything very carefully and can't visually find anything wrong. Did you use a hair dryer or other heat source to get the digitizer off? Perhaps the radio portion received to much heat and fried. That the only thing I can think of.

When I first did the repair, I ripped the ribbon from mother board to digitizer, not realizing it was there in the first place. The screen separated from the digitizer pretty easily, no heat required.
The new piece I ordered had the digitizer and outside bezel all attached as one piece, which would normally be two pieces. While constructing everything, I forgot that little rubber/plastic piece that fits near the front facing camera, so I detached the mother board connections, then went down to the antenna area and disconnected the micro coax and the connector slipped off the cable altogether. I put the exposed wire back into the connector, restarted the phone, and there has been no signal ever sense.
The last thing I'm going to try is getting an OEM micro coax from either a P990 or P999. I feel kind of stupid for worrying about this, since it's an old phone with limited development at the moment, plus I have another phone already. But since I bought an entirely new shell, I want to fix this damn thing and probably just sell it.

Canadian G2X/P999 are branded LG and are known as Optimus 2X even though they are not the P990 Optimus 2X which is/was also sold in Canada, each model sold by different service providers operating on different cell radio bands. At a point, T-Mobile was supplying LG branded G2X/P999 phones as replacements. You probably have one of those or, if you bought it from someone in Canada or who was in Canada that would also explain why yours is branded LG.
If you shorted the antenna cable's internal wire to its shield that would short-circuit the cell radio's output which may have damaged the hardware if the phone transmitted while there was a short-circuit.

I think what I need to do, if i wanted to keep this phone, is the buy a crappy g2x and use it's internal motherboard with antenna and coax cable.
Does anyone know what the board is called at the bottom of the phone, near the charging port? It's where one end of the micro coax cable connects. The other end is near the middle of the phone, on the main mother board.
I'm wondering since the board at the bottom had the problem, if I were to replace that.

Here's the repair manual:
http://www.scribd.com/doc/84937521/70/EXPLODED-VIEW

There is a way to test the cell phone radio to determine if it works but it involves installing some Qualcomm software, QPST and QXDM, which are professional tools for monitoring, testing and modifying the phone's Qualcomm cell radio characteristics. My post about how to fix the P999 IMEI has the download links and instructions for setting QPST up: http://forum.xda-developers.com/showthread.php?t=1942417 I'll find the QXDM link and installation instructions and post it in this thread too.

Finally fixed the damn thing, adjusted the length on either side of the mico coax, the cable isn't being pinched anymore so it works fine. I have a slight problem, though, I have some bright light bleeding from the middle left, and top right of the screen. Maybe because the LED isn't seated flush against the digitizer? Is that what would cause this?
It's minimal, and I don't want to take it apart, but still curious.

Around the screen edge there should be attached to the digitizer a thin foam gasket. If it is missing a piece of the thin foam or if it somehow got disturbed or is not there it most likely is where the bleed is comming from.

[Q]OPO doesn't recognize my sim. Need help guys

Hi All,
I have purchased OPO in september but I got it delivered to India yesterday only. I tried to insert my sim in the correct way like shown in the image, but to my surprise , I am getting the below error.
So I did a research and tried the following steps
Tried the 3g and 2g option. Did a restart.
My sim is actually a micro sim that is not cut from the mini sim. I am using it perfectly in my nexus 4.
Watched the videos on how to insert the sim properly. Did according to that.
So I thought there my be some bugs in the stock( I am on 38R) . So unlocked the bootloader and flashed the CM nightly. Same issue exists.
Then reverted back to stock and updated to 44S. Same issue exists.
The phone is working fine with everything. But it is unable to read my sim. I have tried my dad's sim which is used in Moto G.
So I took a video and posted it on youtube. Please go through it and let me know if I have damaged any of the golden PINs.

Thanks for your patience.

Lol no.

I can see the airplane mode icon in the picture you uploaded.

Try this :
1) Turn Airplane mode ON
2) Turn Airplane mode OFF
3) Reboot your phone (not software reboot, a real one)

This is the error I an getting.

Maybe your Sim is locked or not activated. Try the Sim in another phone.

No man it is working fine in nexus 4.

Even though you mention making sure the SIM is inserted the right way, I just want to confirm;
when looking at the screen, the SIM should be _below_ the tray and facing with the pins to the back.

Do you mean your dad's sim is working in the OPO? Or is it a no-go either? If the first applies; you may want to try having your carrier replace the SIM.
It seems the Oneplus is sometimes a bit tricky regarding the SIM.

Was going to add my voice to this as my opo arrived yesterday and I fell into that trap
I would suggest putting a cloth down on the table then lay the phone screen down,put your sim card in the tray(the only way it can go) and slide it home (that way the sim contacts will be facing you and as the tray goes in (hope that made sense)
If that does not work then contact your carrier about a replacement,fickle things sim cards

Yes you are correct . Its a trap but I did check a youtube video first before inserting the sim . It shows the way you described. But still its a no go. I think my OPO is defective or somehow I may have damaged the sim slot.

difficult for me to say I feel for you if you need to get a new unit as it was tough enough to get that one, would for sure contact your carrier as I think that will be easier than trying to get a replacement, let us know how you go

Yeah looking at the error message it seems to be a problem with the sim card not the phone itself. Correct me if I am wrong.

So i took a new sum from my carrier and used it in my OPO. I hoped that changing the sim might resolve the issue but it didn't. After removing the sim i saw some scratches on the side of the sim. So i thought the golden pins might cause this. So i will go for a RMA. You can see the image of the sim.

That card is toast, that happened putting it into the opo ?

It looks like the pins are bent on your 1+1 to do that damage on the sim card. Was your phone used because sometimes people use sim adapters to fit a nano sim into a micro sim phone and when they try to remove the card/adapter it gets caught in the pins and bends them.

Check water sticker on botton of sim slot

I had the same issue with a board i fitted to G930F bluetooth wasnt working nor wifi for no apparent reason i went through absolute everything firmware wise and system wise and couldnt figure out what the problem was i then removed everything once again looking for a loose connection it turns out the board i fitted in the top right hand corner there is a silver chip that controls wifi and bluetooth under the antenna there was a small black spot i noticed once carefully cleaned up i found the culprit there are 2 tiny fuses that blew conecting to the wifi chip this chip must also control bluetooth and NFC as that no longer works also.

Do you find a solution

I did find the solution unfortunately it requires the wifi ic chip to be replaced along with the fuses accompanied to the chip on the logic board but that means micro soldering the new chip on the other solution is change the board out when you take the antenna at the top off at the top right is the silver chip look at the circuitry and you should find a black burnt out spot also check the aerial for plastic burn where the chip sits
Thats the only solution available that ive found, not even the factory binary found the issue with the hardware though
That one chip though controls the wifi/bluetooth/android hostspot/NFC funnily enough though even though its blown visually the wifi toggles on still and will every now and then pick a network up for a second, the bluetooth toggles on but will not find any other device and other devices cannot find it either, the android hotspot turns on and broadcasts a signal but when trying to connect to it it will not connect, the NFC toggle is also set to on with the writing and toggle greyed out and NFC apps asking to turn on the chip but it cannot be toggled these are symptoms of the error,
If you would like to inspect your device,
If you dont know what your doing order a new backing i can successfully remove them without cracking them with a hair dryer, screen puller the cheap ****ty ring ones, and a guitar pick,
To start heat the backing of the phone up with hair dryer until its warm/hot next step is my secret trick to pop the watertight seal take the sim tray out and no **** blow into it youll hear the seal break get the ring puller pull it up enough to get the guitar pick in and just slide it all the way round,
Once the backs off theres 3 screws at top on antenna your gonna wanna use a phillips #00 for them once the screws are out get a pair of tweezers and slide them into the slot on the left side of the antenna where the vibrator is and pull up it will probably go flying if you use to much force but it wont break, the circuit and wifi module are now exposed on the top right diagnose the board for burnt spots if there is there, take the NFC chip off below the antenna and then the speaker to expose the charging port check the bottom right hand corner for circuitry burning also.

Hi, I have same problem for long, I tried all software options: factory reset, network reset, hard reset, wipe, firmware upgrade, downgrade,,
I can use NFC without problem but WiFI and Bluetooth are greyed out or stucking on turn on without finding anything.
Could you confirm what is the right IC for it ? I found two different IC number one on Ebay another on Part4reparirs , not sure which one is legit as both claim to be G930 wifi-IC (can't add link as I am new user)
also I would be interested to know where to buy fuse for it
I really miss my phone for few month using spare xiaomi now

Hey mate im a phone technician,
Ive got a few boards qnd broken S7 laying around ill pull one down and take a picture and label it and what not & will post it here for you,
The ic chip isn't actually a fuse its an actual chip which controls the wifi and bluetooth functions of the phone NFC is locted on 2 different part of the board aswell as wireless charging coil etc, so if that stuffed best of getting a new board, but however there is a small thermistor (ThermalTransistor) just before the wifi bluetooth ic hopefully for you its blown that and stopped current before getting to the wifi ic, i will also label this in the diagram
Hopefully in your case its the thermistor youll know anyway if it is will be blown with black or white residue everywhere and your antenna may be partially burnt out in that case, you will also need to check the daughter board for black or white burn residues also in the bottom right hand corner ill take a picture and label again also,
If i cant get the pics up straight away for you its because xda app is being a pain in the ass still and wont let me upload being playing up for a week now
